Solutions

No. 1 Porter-Matthews (2010 Jamaican Nationals, Kingston, Jamaica)
This is game ends with an instructive tactical flurry. Porter ends the game swiftly with 34.Rbe1! Qd8 35. Bxd7! undermining after 35Qxd7 36. Bxf6+. Black resigned in lieu of 36...Kxf6  37.Rxh6+ mating. (See game)

No. 2  Thomas-Matthews (2010 Jamaican Nationals, Kingston, Jamaica)
This was a nice sacrifice showing that the seven-time National Champion had a good understanding of  the strength of his passed pawn and the fact that the knight is such a clumsy defender against the  a- and h-pawns. Thus, he decided to play 51h4! After 52. Nf6+ Kg3 53.Nxd5 h3 54. Ne7 h2 55.Nxf5 Kh3 and the pawn will queen. (See game)

No. 3  Matthews-Wisdom (2010 Jamaican Nationals, Kingston, Jamaica)
Another instructive finish by Matthews this time an exchange sacrifice designed to support a dangerous passed pawn. White finished with 33.Rxe5! fxe5 34. 34. Bb6 Kg6 35. Kc4 Kf5 36. Kc5 Ra8 37.Kxc6 Ke6 38.Kb7 and black will not be able to stop the a-pawn. (See game)

No. 4  Wisdom-Byfield (2010 Jamaican Nationals, Kingston, Jamaica)
This game was a total disaster because black had a clear win. Instead black played the fatal 43f7-f6 and was met rudely with 44.exf6! (all other moves lose) 44gxf6 and now 45. h5! Kxd6 46. h6 1-0 (See game)
