Handicap rules

Computation of handicaps: The ELO of each player according to the FESA rating list from June 20, 2024, will be converted into a fractional grade. By the table from point 2 of the FESA rating regulations http://fesashogi.eu/index.php?mid=5&listid=elosystem, the ELO of a player lies in a rating range of a certain grade g between a lower bound ELO LB and an upper bound ELO UB. The fractional grade frac.g is computed as follows (rounded to one decimal place):

frac.g = g + (ELO-LB)/(UB-LB)

The fractional grade may differ from the actual grade of a player. The fractional grade of a player without a FESA rating will be estimated in accordance with their playing strength.

Example:
A player’s ELO is 1847. The corresponding grade is g = 2 dan. The values for LB = 1800 and UB = 1920 yield the fractional grade frac.g = 2.4 dan.
A player’s ELO is 1355. The corresponding grade is g = 4 kyu. The values for LB = 1280 and UB = 1360 yield the fractional grade frac.g = 3.1 kyu.

The difference of the fractional grades between two players determines the handicap:

0-0.5: no handicap, equal game
0.6-1.4: left lance
1.5-2: bishop
2.1-2.6: rook
2.7-3.5: rook and left lance
3.6-4.9: 2 pieces (rook and bishop)
5.0-6.4: 4 pieces (2 pieces plus both lances)
6.5-7.9: 5 pieces (4 pieces plus right knight)
8.0 and above: 6 pieces (4 pieces plus both knights)

Example: The difference of the fractional grades of the two players from the above example is 4.5. The corresponding handicap is two pieces.

Further rules: In case of jishogi (mutual entering kings), the handicap giver gets credit for the pieces removed at the start. In case of sennichite (move repetition) or a tied jishogi count, the handicap giver wins.
