AU vs Nusa Mahkota

Goldis and SMS Gold was the top team in the first DATCC Team league which concluded a few months ago. In the second edition , two team - AU and Caviaga is the teams to be beaten. They are the favourite to win this league. In round 1, my team Nusa Mahkota was grown down 0-4 to the AU team. I myself lost to "Jax Attack" on board 3.

2nd DATCC Team League (Round 1)

The position ( see diagram below) is more or less equal but i blunder big time with...

26.Ra2? This is the decisive mistake. I should not abandon my last rank and should choose 26.Rf1 instead 26...fxg3 27.hxg3 27.Qxg3 will not fair better for e.g 27...Qc1+ 28.Bf1 with the threat like 28...Rf5 and Rg5 look dangerous for white 27...Qc1+ 28.Bf1 Rf3 At first i didn't noticed the dangerous coming from this move 29.Qb2 Rxg3+! I completely missed this move 30.Kh2 ...This position deserve a diagram... 30...Qh6+! 31.Kxg3 Jax sacrifice a rook for mating attack 31...Qf4+ 32.Kh3 Bf5+ 33.Kg2 Be4+ 34.f3 Qxf3+ 35.Kh2 Qxf1 36.Rxb7 Qh1+ 37.Kg3 0–1

Yours truly - Jax Tham 0-1
