TeamLeague T38: My 4th Round Game

In round 4 of TeamLeague, my game was left to be played last for my team. We were leading 2-1 before my game started, so I needed at least a draw to secure the team win.

I came out clearly worse of another declined Benko gambit, but my opponent failed to capitalize on my choice of opening, and we eventually reached an even rook endgame (the 2nd diagram below). However, that endgame was badly mistreated by yours truly…

Interesting to note is that in all four games, my opening gambits have been declined. Party-poopers!

22...Re8+?

[22...Ra6 is more active, and the correct way to play this rook endgame. The text move leads to a clearly better and more active position for White. 23.a3 Rb8 24.Rc2 Re6+ 25.Kd3 Rb3+ 26.Kxd4 Rd6+ 27.Kc4 Rxb2 28.Rxb2 Rxd1 29.Rb7+ Kg6 30.Rxa7 Rd2=]

[37...Rb7 puts up a tougher defense, but White is winning in any case. The rest is just a formality.]
