(2) Tomkovich,Greg (1659) - Moldovan,John (1814) [E13]
21st Kenilworth Championship Kenilworth (5), 10.02.2011
[Moldovan & Houdini 1.5a]
E13 Queen's Indian Defense
[In the 2nd round against Mazzillo, Greg opened with 1.c4
& I thought he might do so again.]
A little move-order twist. [Over the years (2005-2010), we've repeatedly explored 1...e6
(7x) and worn it out.; 1...g6
, as in our 2010 Summer Tourney game, was considered but, despite success there, I didn't want to repeat. With a 2nd tier defense, you want to hit and run, to avoid getting caught in a prepared line.]
I was pleased to see this. [I expected 2.Nf3
& some damned system.]
[In the 2008 KST he chose 3.Nc3
& I won :-)]
[In round 3 against Kevin Chen, I opted for 3...Bb4+
& lost :-(]
see Komunicky - Chen from round 1, Renna - Mangion from the 2008 Ellner Memorial & my 2006 win vs. Shiffman.; For 4.g3
see my 2008 STC Ch. draw vs.J.P. Singh.]
The ...Bb4 + b6 setup has been my favorite for 30 years but, due to frequent use of the Bogo and Dutch orders, this form hasn't seen much tournament action.Diagram
see my 1991-92 win vs. LoPresto (as White).]
This is main line. [For 5.g3
see my 2005 win vs. Lin.; For 5.e3
see Pawlowski - Mangion : 2009 KST.; & for 5.a3
see Agress - Mangion from the 2008 Championship.; There is also Seirawan's 5.Qb3
; Miles' 5.Bf4
and 5.Qc2.; Here's an example of the latter: 5.Qc2
L. Epstein - Moldovan : 2nd Saturday Swiss #5, Kenilworth 06/08/1991 12...Nbd7=
maybe White's best.; For 6.Qc2

is the litmus test of my inaccurate 8th.]
Now Black can meet e4 with ...e5 and break the pin without resorting to ...g5 or risking doubled f-Ps.
This aims to slow/stop ...c5 and/or prepare (after ...e5) a possible Nh4-f5... [... But >=11.Nd2

Overall, there have been 85 games with 9 other moves.]
also looks good.]
[I didn't want to expose my K unnecessarily with 12...Nh5
; or give White 12...e5
; Trading-off my Bb7, with 12...Bxf3
was also out of the question, even in conjuction with an exchange of the d.s. B via 13...Nh5
; & I rejected 12...c5
because I wanted to leave c5 open for a N.; So, a waiting move was in order. My ...Rac8, which protects c7 and supports a possible ...c5 advance, is reasonable enough but I'm not sure it was best. Let's look at all the candidates and see how they compare:
Since I haven't played ...f5 or committed to such a plan, there's no problem on the a2-g8 diagonal and no need for 12...Kh8
; After 12...a6
the threat of a4-a5 would just make me play 13...a5
, straight away, is better than ...a6 but, in a future ...e5, dxe5 dxe5 sequence, I'd be without ...Nb8-c6-a5.; That leaves us with other R moves.
protects the Q and readies her retreat to f8, in case White brings the B back to h4 or meets ...e5 with Nh4-f5. But, on the minus side, it loses a tempo in future ...Nh5, ...g5 + ...f5 lines.; 12...Rab8!?
, which has the benefit of protecting the Bb7, keeping c8 open for him and preparing ...b5, seemed too phony at the time and would have put the R in the Bf4's sights. But, it could have saved me 2 tempi vs. the game.
All 10 moves, though, are playable and at least =.]
This makes White's l.s. B bad. [>=13.h3
although Black can take/force a draw with 14...Bxf3
was an alternative.]
Some more temporization. [I could have grabbed a P with 14...exd4
but that would have repaired White's structure and freed his game.]
This shuts my Bb7 out of play for a while but closing the center and yielding the c5 square is exactly what I want. [>=15.Rae1
maintaining the duos (c4+d4, d4+e4) and tension.]
>= Bxf4 =/+, here or on his next 2 turns.
but I didn't see the benefit of trading good N for bad B.]
Diagram A big tactical mistake. White gets away with it once... but not twice.
Overly concerned with preventing Ba4... [... I miss 18...Nxh3+!-/+
Now I see the trick but, in this version, my opponent has a R-lift, gets several tempi & doesn't lose a 2nd P.
White is going to double on the g-file. So, I might as well move my K off it.
This primarily defends the g7 focal point but a K-side build-up with ...g5 + ...Rg6 & ...Rcg8 may be in the position.
[I wanted to play 25...Bxc4
but had a hallucination...; ... and somehow thought ( 25...Bxc4
was +-. No you smart-asses, this time I had my glasses on.]
/\s of ...b5 & ...Bc8Diagram [>=27...g5

would have given me a new target and forced him on the defensive.]
If my K was still on h8, White would really have 31.Qxh6! gxh6 32.Rxg8#. So, you see, my concern at move 25 had some basis.

Threatening mate in 2 at h2.
Trading down to R+5 vs. R+3 (on moves 38-41) is good enough... [... But 38...Qxe4+
, when Black, at the very least, wins Q for R, was more convincing.]

Diagram White resigns
Houdini claims the final position is just -/+ but Fritz 12 says it's -2.71 and HIARCS 11 judges it -1.75.
Some of the free UCI engines, even strong ones, can't access endgame tablebases. That certainly is the case here.
Time left - Tomkovich 50:41, Moldovan 20:14
Estimated time used - Tomkovich 37:44, Moldovan 68:11
Longest think by White - 4 minutes for 30.Qe3
Longest think by Black - 5 minutes for 12...Rac8
With the win, I finished clear 3rd, with a 3.5-1.5 score & a mediocre 1826 PR.
