Eight men had participated in the chess tournament. (Each meets each, draws are allowed, giving $1/2$ of point, winner gets $1$.) Everyone has different number of points. The second one has got as many points as the four weakest participants together.  What was the result of the play between the third prizer and the chess-player that have occupied the seventh place?
1. **Labeling and Initial Setup:**
   Let the participants be labeled as \(a, b, c, d, e, f, g, h\) in order from first place to last place. We are given that:
   - Each participant has a different number of points.
   - The second participant has as many points as the four weakest participants together.
   - The total number of points is 28.

2. **Points Distribution:**
   Let the points of the participants be \(a, b, c, d, e, f, g, h\) respectively. We know:
   \[
   a + b + c + d + e + f + g + h = 28
   \]
   and
   \[
   b = e + f + g + h
   \]

3. **Assigning Points:**
   Since everyone has different points and the total is 28, we can try to assign points that satisfy both conditions. Let's assume:
   \[
   a = 7, \quad b = 6.5, \quad c = 5, \quad d = 3, \quad e = 2.5, \quad f = 2, \quad g = 1.5, \quad h = 0.5
   \]

4. **Verification:**
   - Check the total points:
     \[
     7 + 6.5 + 5 + 3 + 2.5 + 2 + 1.5 + 0.5 = 28
     \]
   - Check the second condition:
     \[
     b = e + f + g + h \implies 6.5 = 2.5 + 2 + 1.5 + 0.5 = 6.5
     \]
   Both conditions are satisfied.

5. **Determining the Result of the Play:**
   We need to determine the result of the play between the third prizer (participant \(c\)) and the seventh place player (participant \(g\)).

6. **Directed Graph Analysis:**
   Since \(c\) has 5 points and \(g\) has 1.5 points, and given that everyone has different points, it is reasonable to assume that \(c\) won against \(g\). This is because \(c\) has significantly more points than \(g\), indicating a higher number of wins or draws against other participants.

Conclusion:
\[
\boxed{\text{The third prizer won the game against the seventh place player.}}
\]
