[I guess he was counting on 15.Bxh8?? Bb4# ]

This lets me develop my l.s. B, kick the Rh7 around and displace Black's K. [>=15...Rg8 16.Be5 Nd7 17.Bg3 Be7+/- ]

19.hxg5?
This slip gives Black a chance to get back in the game. [19.Be5 Bd6 20.Bxd6 Kxd6 21.hxg5 hxg5 22.Rh8+- was right.]

19...hxg5?
[We missed 19...Nd7! 20.Rh5 Nxf6 21.gxf6 c5+/- ]

20.Be5
Now White is winning again & the N never gets off the back row.

20...Rc8?
[20...Bd6 21.Bh8! Nd7 was a much better try.]

21.e4
Threatening to win the Rc8 with an x-ray check.

21...Bb4+
Too late... 7 moves late.

22.Ke2 Rg8
[>=22...Rf8 but after 23.Rh7 White's mating menace would cost Black an Exchange.]

23.Bf5+
Black resigns. Time left - Moldovan 50:00, Shumowitz 46:13 Estimated time used - Moldovan 26:55, Shumowitz 28:42 Longest think by White - 5 minutes for 21.e4 Longest think by Black - 5 minutes for 12...Bxe4 Btw, Marvin took less than a minute for 14...Bxf3? & I spent the same on 19.hxg5? [After 23.Bf5+ Ke7 24.Rh7+ K moves 25.Rxb7 White will, at the very least, pick-up a 3rd P.] 1-0
